There exist some other Pi compatible system with a litle more Umph... like Pine64, &nbsp;64bit quad-core &nbsp;processor, 2GB mem (up to 4GB) <br />

there are others, there is a kit with housing, touchscreen &nbsp;etc.

Trying to build a mini PC that is capable of doing OCR with a limited list of characters (17 total). &nbsp;Currently working on OCR but QR code could be a option.<br />
It will need to scan for input and save the data (along with location, time and a few other pieces of data) to a online database via wifi (not hard wired).<br />
We have done some testing with a Pi but it does not have the processing power needed. &nbsp;Results are 20%-44% accurate.<br />
So I am looking for suggestions on a mini computer we could do testing on that could handle everything with 99.9% accuracy.<br />
Device requirements:<br />
1) small 4&quot;x3&quot; ish size<br />
2) On board WiFi<br />
3) Attachable mini camera for data scaning<br />
4) Attachable mini touchscreen (4&quot;x3&quot;)<br />
5) On board GPS<br />
We are looking at LattePanda or odroid xu4. &nbsp;But I need some feedback on if either of them will work or if there are other options.

Selecting a mini computer

Databases are organized collections of data, most commonly accessed through management systems including schemas, tables, queries and processes that allow users to enter and manipulate the information or utilize it in other fashions, such as with web applications or for reporting purposes.

Databases

A miscellany is defined as a "collection of various pieces of writing by different authors", but it has come to mean something "Of items gathered or considered together of various types or from different sources" or "a collection or group composed of members or elements of different kinds". The word "miscellaneous" comes from the Latin word "miscere", meaning "to mix." You might have heard the expression "a mixed bag," which applies when you don't quite know what you're going to get. More commonly, a miscellaneous group is made up of an odd group of things that don't fit anywhere else.

Miscellaneous

A personal computer is a general-purpose computer whose size, capabilities and price make it useful for individuals, and is intended to be operated directly by an end-user with no intervening computer time-sharing models that allowed systems to be used by many people, usually at the same time. Personal computers may be connected to a local area network (LAN), either by a cable or a wireless connection, and through that to the Internet. A personal computer may be a laptop computer or a desktop computer running an operating system such as Windows, Linux or Macintosh OS.

Optical character recognition (OCR) is the mechanical or electronic conversion of images of typed, handwritten or printed text into machine-encoded text. It is widely used as a form of data entry from printed paper data records, including passport documents, invoices, bank statements, computerized receipts, business cards, mail, printouts of static-data, or any suitable documentation. It is a common method of digitizing printed texts so that it can be electronically edited, searched, stored more compactly, displayed on-line, and used in machine processes such as machine translation, text-to-speech, key data and text mining. OCR is a field of research in pattern recognition, artificial intelligence and computer vision.
